In the world today, many people prefer to keep their money in their house save because of the perceived fraud by our traditional banking system that has decided to rip the populace off their hard-earned money without remorse, through different unexplainable charges
You think that nowadays many people keep their money at home, rather than in the bank. In my opinion, all of this has not really happened completely, and currently there are still many people who still use banks (the majority).
In fact, currently the bank is making too many profits from its customers, and all of this has been going on for a long time and nothing can make the bank's system change.
But what I experienced where I live, many people around me are not aware of it. So even though the current banking system is quite draining of money for its customers. But what I know from real events, customers in my area, don't really care about that. So maybe the incident is different from what you mentioned, or what you experienced around where you live.
So in conclusion, the current bank users, especially those in my country, are still in the majority and maybe in other countries the users are still in the majority.
I want to categorically tell this set of people that Bitcoin is the way forward for you, bitcoin works for everyone, and the system was designed in a way that every interested person can participate.
It's true, bitcoin might be a light for a very dark banking system. But even so, it still takes a long time to convince people or tell someone about bitcoin. Because most of the minds are familiar with what existed before bitcoin existed.
So even though bitcoin can be good for them, if they are hard to get involved in, it's still useless.
